https://en.wikiversity.org/wiki/Free_Energy_does_not_Exist I'm an EV enthusiast. I own a RAV4EV from 2002. Its NiMH battery pack is dead; unable to hold a charge beyond a few seconds. So, I endeavor to understand how a load (a motor) can contribute to the generation of its own power by reversing the polarity of its current! But since this knowledge is a hard sell, I word the title of my text (up-above) cautiously in a conservative manner paying homage to the 'con' facts before I spell out the pro's. But you know what? No one should be the first to cast a stone since the fault does not stop with me for promoting such a crazy idea. It gets worse. You won't hear about this on the evening news, 'cuz it's not good for business. It's only good for the consumer. Oh, well!
